DNN Platform 9.3.2 /
2sxc 10.25.2
I have a DNN website that uses 2sxc. I created a "Notification Bar" content type and c# razor template that I use to display special notifications to the user. This module is meant to display on every single page of the website. I used the "Add Existing Module" functionality to manually add the module to every page but it's a bit cumbersome and I run the risk that my Content Editors move the module by accident, delete, or forget to add it to new pages.
Is there a special 2sxc skin object that I can use inside of my .ascx DNN skin to load a 2sxc module so that I don't have to add it to every page through DNN? Apparently there is one in DNN OpenContent.
(More than just the notification bar, this would be super useful for the site's header or footer that gets occasionally updated. For example, social media links, contact info like address or phone number, or other links that aren't part of the DNN pages menu.)
There are two ways
create a pane for this specific module (it's the easiest to edit and work with) and just show the module on all pages
create the module on a hidden page and then inject it into the skin, using the Factory to get the CmsBlock - see https://docs.2sxc.org/api/dot-net/ToSic.Sxc.Dnn.Factory.html#ToSic_Sxc_Dnn_Factory_CmsBlock_System_Int32_System_Int32_
Daniel, this is how we did it in the past. I notice your call is similar but simpler (above in the comments). Is that because the API changed somewhere after v10?
<script runat="server">
// get 2sxc to Render() the output from the module on the SITE/Manage Flyout Links page
private IHtmlString RenderFlyoutMenu()
{
return ToSic.SexyContent.Environment.Dnn7.Factory.SxcInstanceForModule(3354, 606).Render();
}
</script>
<%=RenderFlyoutMenu() %>
So I have a curious situation and I don't think it's going to work, but I figured I'd ask in case it is and someone knows how to. I am using a 3rd party website to create marketing funnels. You can add your own custom html and javascript, but it parses out the html in a rather unfavorable manor. Basically you specify an element on the page and it appends it as a data attribute and dynamically loads it into the DOM. Since this is happening this way, my app isn't being initialized because it's not in the DOM on page load. Is there a way to make this work? I'll explain a little deeper my configuration.
I add custom html such as:
<div data-ng-app="AppName"><div data-ng-controller="ControllerName"><div>perform controller logic here</div></div>
As you can see, this needs to be in the DOM for the app to initialize and, well work. Is there a way to initialize the app after the page has loaded dynamically? I can add my own JS files in the custom html field, but thats about as far as I can go for customization. Any help is appreciated!
Maybe you should execute angular's bootstrap function manually in your script after the required dom loaded.
var app = angular.module('appName', []);
app.controller([...]);
angular.bootstrap(document.getElementById('divId'), ['appName']);
For more information, you can see this doc https://docs.angularjs.org/api/ng/function/angular.bootstrap
I need to scrape some URLs from some retailer product pages, but the specific URLs I need to get aren't in the html part of the page. The html looks like this for each of the items on which one would click to get to the page with the URL I need to grab:
<div id="name" class="hand bold" onclick="AVON.productcontrol.Go(45714);">ADVANCE TECHNIQUES Color Protection Conditioner Bonus Size</div>
I wrote the following to get URLs from the page, but since the actual URLs I need don’t seem to be stored in the page, it doesn’t get what I need:
def getUrls(URL):
"""input: product page url
output: list of urls to products
"""
connection = urllib.urlopen(URL)
dom = lxml.html.fromstring(connection.read())
selAnchor = CSSSelector('a')
foundElements = selAnchor(dom)
urlList = [e.get('href') for e in foundElements]
return urlList
Is there a way to get the link that the function after ‘onclick’ (I guess AVON.productcontrol.Go(#);) takes you to? I don’t fully understand html, and while I’ve read a bit about onclick, I can’t figure out how the function after 'onclick' works.
In order to find the URL that you are taken to on click, you need to find the JavaScript source code of the 'Go' function and read and understand it. It's buried somewhere within a tag or some JavaScript .js file that is referenced directly or indirectly by the HTML page. Happy digging!
Or: you automate the interaction with the web page with a tool like Selenium (http://docs.seleniumhq.org/) and just check where it takes you if you click.
I´m implementing facebook comments boxes on my news pages. And it works. The problem is that if I make a comment on one page, it will display on ALL pages which contains fb comment boxes.
Currently my code looks like this:
<b><div class="fb-comments" data-href="http://selandia-ceu.dk/selandia/nyheder.aspx" data-num-posts="3" data-width="500"></div>
<script>
var fb-comments = document.getElementById('fb-comments');
mydiv.innerHTML =
'<div class="fb-comments" data-href="' + document.location.href + '" data-num-posts="3" data-width="500"></fb:comments>';
FB.XFBML.parse(fb-comments);
</script></b>
The website is using Microsoft Server. The url in the code is supposed to refer to the current page one is viewing. Anyone know what I´m supposed to do? :)
The comments are temporary disabled on the pages.
I got the extra bit of code (FB.XFBML.parse) from this thread:
Different Facebook comment box after each ajax call
You may need to clean up your Open Graph tags, as the URL that each comments plugin is pointed to will be scraped by the Open Graph linter and used to determine the canonical URL. The problem is likely that your comments plugins all end up pointing to the same canonical URL:
https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fselandia-ceu.dk%2Fselandia%2Fnyheder.aspx
Use this Debug tool to inspect your Open Graph tags and ensure each page has it's own canonical URL. You also need to correct the fb:admins tag that you have in your HTML as suggested by the debugger.
I'm currently trying to build a new website, nothing special, nice and small, but I'm stuck at the very beginning.
My problems are clean URLs and page navigation. I want to do it "the right way".
What I would like to have:
I use CodeIgniter to get clean URLs like
"www.example.com/hello/world"
jQuery helps me using ajax, so I can
.load() additional content
Now I want to use HTML5 features like pushstate to
get rid of the # in the URL
It should be possible to go back and forth without a page refresh but the page will still display the right content according to the current URL.
It should also be possible to reload a page without getting a 404 error. The site should exist thanks to CodeIgniter. (there is a controller and a view)
For example:
A very basic website. Two links, called "foo" and "bar" and a emtpy div box beneath them.
The basic URL is example.com
When you click on "foo" the URL changes to "example.com/foo" without reloading and the div box gets new content with jQuery .load(). The same goes for the other link, just of course different content and URL.
After clicking "foo" and then "bar" the back button will bring me back to "example.com/foo" with the according content. If I load this link directly or refresh the page, it will look the same. No 404 error or something.
Just think about this page and tell me how you would do this.
I would really love to have this kind of navigation and so I tried several things.
So far...
I know how to use CodeIgniter to get the URLs like this. I know how to use jQuery to load additional content and while I don't fully understand the html5 pushstate stuff, I at least got it to work somehow.
But I can't get it to work all together.
My code right now is a mess, that's the reason I don't really want to post it here. I looked at different tutorials and copy pasted some code together. Would be better to upload my CI folder I guess.
Some of the tutorials I looked at:
Dive into HTML5
HTML5 demos
Mozilla manipulating the browser history
Saner HTML5 history
Github: History.js
(max. number of links reached :/)
I think my main problem is, that everybody tries to make it compatible with all browsers and different versions, adds scripts/jQuery plugins and whatnot and I get confused by all the additional code. There is more code between my script-tags then actual html content.
Could somebody post the most basic method how to use HTML5 for my example page?
My failed attemp:
On my test page, when I go back, the URL changes, but the div box will still show the same content, not the old one. I also don't know how to change the URL in the script according to the href attribute from the link. Is there something like $(this).attr('href'), that changes according to which link I click? Right now I would have to use a script for every link, which of course is bad.
When I refresh the site, CodeIgniter kicks in and loads the view, but really only the view by itself, the one I loaded with ajax, not the whole page. But I guess that should be easy to fix with a layout and the right controller settings. Haven't paid much attention to this yet.
Thanks in advance for any help.
If you have suggestions, ideas, or simple just want to mention something, please let me know.

I've put up a successful minimal example of HTML5 history here: http://cairo140.github.com/html5-history-example/one.html
The easiest way to get into HTML5 pushstate in my opinion is to ignore the framework for a while and use the most simplistic state transition possible: a wholesale replacement of the <body> and <title> elements. Outside of those elements, the rest of the markup is probably just boilerplate, although if it varies (e.g., if you change the class on HTML in the backend), you can adapt that.
What a dynamic backend like CI does is essentially fake the existence of data at particular locations (identified by the URL) by generating it dynamically on the fly. We can abstract away from the effect of the framework by literally creating the resources and putting them in locations through which your web server (Apache, probably) will simply identify them and feed them on through. We'll have a very simple file system structure relative to the domain root:
/one.html
/two.html
/assets/application.js
Those are the only three files we're working with.
Here's the code for the two HTML files. If you're at the level when you're dealing with HTML5 features, you should be able to understand the markup, but if I didn't make something clear, just leave a comment, and I'll walk you through it:
one.html
<!doctype html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js"></script>
<script src="assets/application.js"></script>
<title>One</title>
</head>
<body>
<div class="container">
<h1>One</h1>
Two
</div>
</body>
</html>
two.html
<!doctype html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js"></script>
<script src="assets/application.js"></script>
<title>Two</title>
</head>
<body>
<div class="container">
<h1>Two</h1>
One
</div>
</body>
</html>
You'll notice that if you load one.html through your browser, you can click on the link to two.html, which will load and display a new page. And from two.html, you can do the same back to one.html. Cool.
Now, for the history part:
assets/application.js
$(function(){
var replacePage = function(url) {
$.ajax({
url: url,
type: 'get',
dataType: 'html',
success: function(data){
var dom = $(data);
var title = dom.filter('title').text();
var html = dom.filter('.container').html();
$('title').text(title);
$('.container').html(html);
}
});
}
$('a').live('click', function(e){
history.pushState(null, null, this.href);
replacePage(this.href);
e.preventDefault();
});
$(window).bind('popstate', function(){
replacePage(location.pathname);
});
});
How it works
I define replacePage within the jQuery ready callback to do some straightforward loading of the URL in the argument and to replace the contents of the title and .container elements with those retrieved remotely.
The live call means that any link clicked on the page will trigger the callback, and the callback pushes the state to the href in the link and calls replacePage. It also uses e.preventDefault to prevent the link from being processed the normal way.
Finally, there's a popstate event that fires when a user uses browser-based page navigation (back, forward). We bind a simple callback to that event. Of note is that I couldn't get the version on the Dive Into HTML page to work for some reason in FF for Mac. No clue why.
How to extend it
This extremely basic example can more or less be transplanted onto any site because it does a very uncreative transition: HTML replacement. I suggest you can use this as a foundation and transition into more creative transitions. One example of what you could do would be to emulate what Github does with the directory navigation in its repositories. It's an intermediate manoever that requires floats and overflow management. You could start with a simpler transition like appending the .container in the loaded page to the DOM and then animating the old container to {height: 0}.
Addressing your specific "For example"
You're on the right track for using HTML5 history, but you need to clarify your idea of exactly what /foo and /bar will contain. Basically, you're going to have three pages: /, /foo, and /bar. / will have an empty container div. /foo will be identical to / except in that container div has some foo content in it. /bar will be identical to /foo except in that the container div has some bar content in it. Now, the question comes to how you would extract the contents of the container through Javascript. Assuming that your /foo body tag looked something like this:
<body>
foo
bar
<div class="container">foo</div>
</body>
Then you would extract it from the response data through var html = $(data).filter('.container').html() and then put it back into the parent page through $('.container').html(html). You use filter instead of the much more reasonable find because from some wacky reason, jQuery's DOM parser produces a jQuery object containing every child of the head and every child of the body elements instead of just a jQuery object wrapping the html element. I don't know why.
The rest is just adapting this back into the "vanilla" version above. If you are stuck at any particular stage, let me know, and I can guide you better though it.
Code
https://github.com/cairo140/html5-history-example
Try this in your controller:
if (!$this->input->is_ajax_request())
$this->load->view('header');
$this->load->view('your_view', $data);
if (!$this->input->is_ajax_request())
$this->load->view('footer');
